Sourcing & Materials — Seathrou

Sourcing & Materials


Seathrou is curated, not manufactured. We choose pieces — we do not make them. There is no atelier behind this label and no workshop we can show you. What we do is select: a small wardrobe drawn from a wholesale catalogue and a curated designer edit, held to one bar before anything earns a place in the range.

This page is about that bar — how we read a piece, and what we keep. Not where it was made, because that is not ours to claim.

How we read a fabric

Most decisions are made by hand and eye, against the same set of questions. A piece either answers them or it does not.

  • Stretch recovery. Does the elastic come back after it has been worn, or does it stay stretched?
  • Opacity. Does it stay opaque under real light, or does it disappear when you don't want it to?
  • Hand. How it feels against skin — the difference between something you keep on and something you take off.
  • Drape. Whether it hangs and moves, or sits stiff and clings.
  • Breathability. This is warm-climate clothing. It has to be wearable at noon.
  • Wash behaviour. Whether it survives ten washes still looking like the piece you bought.

Where we cannot verify a fabric from what's in front of us, we say so, and we request a physical sample before it goes live. We do not assess what we cannot see.

How we read the make

Fabric is half of it. The other half is construction — and it is where cheap pieces give themselves away.

We look at seam placement and finish, at how closures are built (snap, hook, invisible), at whether a piece is lined and lined well. On straps we check width and adjustability. On bodysuits, the gusset. Everywhere, the edge finish — the small tell that separates a considered piece from a fast one.

What's in the range

We keep the list short on purpose. A few categories, each chosen against the lenses above.

  • Swimwear — mostly polyamide and elastane, sometimes polyester. Standard swim construction, judged on recovery, opacity, and how it holds up to salt, sun and rinsing.
  • Bodysuits — viscose, polyester and cotton blends, usually with a little elastane for recovery. The piece lives close to the body, so stretch recovery, opacity and the gusset decide it.
  • Skirts — cotton, denim, viscose, jersey and faux leather, depending on the piece. Weight and structure decide: whether it holds a line or drops a drape, and which it is meant to do.
  • Bags — some are genuine leather and suede, where hand and finish carry the piece; others are faux leather or fabric. We name which is which and don't blur the line between them.

The Sea Edit

Alongside the range, we keep a curated edit of designer swimwear — Gucci, Versace, Brunello Cucinelli, Eres, Zimmermann and others — chosen the same way as everything else: by the lenses above, not by the label on it. These are pieces we selected, not pieces we made. The name on them is theirs.

Where we stop

We don't claim what we can't stand behind. No origin story, no production claims, no sustainability badge we haven't earned. Care guidance is offered as recommended care for a piece's stated composition — standard practice for the materials, not a manufacturer's instruction, because we are not the manufacturer.

Almost nothing. Almost everything. Chosen, not made — and held to the same bar either way.
